Well, that’s it then - go and look at the OR600 Atlas for sale in the UK. Great engine based on the 500 - 8 valve head, single Dellorto DVLA40 carb as used on Alfa’s and other engines, quality suspension and other equipment. They are a tall ride, as Marty said, and obviously heavier than a Chott and more dual purpose.
Parts through Piet or Wolfgang..
I’m glad I got one, was looking at a MX250 before I got it, suits me better..
